How is Ozone Made?
Medical ozone is made by passing 100% pure oxygen gas through a tube (corona discharge) through which electrical energy is directed. The energy breaks apart the oxygen molecules, and what emerges from the other side is a mixture of oxygen and ozone.
Ozone comprises only about 2% to 5% of the gas that comes out of a corona discharge medical ozone generator, with the remaining 95% to 98% being oxygen. Ozone gas has a half life of approximately 1 hr at room temperature, however, cooling it will increase the half-life.
Methods of Ozone Generation
Ultraviolet (UV) – At 185 nm generates a low concentration O3. Comparable to naturally occurring ozone.
Corona Discharge – Electric spark discharge. Created by lightning and medical ozone generators.
Electrolysis – In-situ generation of ozone in water. Used in high purity water.
Plasma Block – Used in wastewater and bottled water plants.
